D because there are 6 sides to a dice and there are 3 options where the number is bigger than 3. Therefore 3/6 = 15/30
R(x) = 60x - 0.2x^2
The revenue is maximum when the derivative of R(x) = 0.
dR(x)/dx = 60 - 0.4x = 0
0.4x = 60
x = 60/0.4 = 150
Therefore, maximum revenue is 60(150) - 0.2(150)^2 = 9000 - 4500 = $4,500
Maximum revenue is $4,500 and the number of units is 150 units
-3/6 -5/7
-21/42 - 30/42
-51/42
- 51/42 = - 1 9/42
hope this help
5 / 7 i think because 5 divided by 7 would be 5/7 as a fraction and she has 5/7 done
<span>2 <span>14/<span>25 as a mixed number decimal form is 2.56 and exact form is 64/25
hope i helped best of luck :) </span></span></span>
